Talon's earliest memories are the darkness of Noxus' underground passages and the reassuring steel of a blade. He remembers no family, warmth, or kindness. Instead, the clink of stolen gold and the security of a wall at his back are all the kinship he has ever craved. Kept alive only by his quick wits and deft thievery, Talon scraped out a living in the seedy underbelly of Noxus. His mastery of the blade quickly marked him as a threat, and Noxian guilds sent assassins to him with a demand: join their ranks or be killed. He left the bodies of his pursuers dumped in Noxus' moat as his response.

The assassination attempts grew increasingly dangerous until one assailant met Talon blade-for-blade in a match of strength. To his surprise, Talon was disarmed and facing down his executioner's sword when the assassin revealed himself to be General Du Couteau. The General offered Talon the choice between death at his hand, or life as an agent of the Noxian High Command. Talon chose life, on the condition that his service was to Du Couteau alone, for the only type of orders he could respect were from one he could not defeat. Talon remained in the shadows, carrying out secret missions on Du Couteau's orders that took him from the frigid lands of Freljord to the inner sanctums of Bandle City. When the general vanished, Talon considered reclaiming his freedom, but he had gained immense respect from Du Couteau after years in his service. He became obsessed with tracking down the general's whereabouts. Talon's suspicions led him to the doors of the Institute of War, where he joined the League of Legends in order to find those responsible for Du Couteau's disappearance.

"The three deadliest blademasters in all of Valoran are bound to the house of Du Couteau: my father, myself, and Talon. Challenge us, if you dare." ― Katarina Du Couteau

Talon's next auto attack within the next 6 seconds deals additional physical damage. If the target is a champion they will also bleed for 6 seconds, taking additional physical damage each second and revealing their location for the duration.

Talon sends out a volley of daggers in a cone that then quickly return back to him, dealing physical damage to any enemies it passes through. Each enemy can only be damaged once at the start of the ability and once at the end. Additionally the enemy is slowed for 2 seconds, refreshing the duration of the slow if they are hit twice.

Talon disperses a ring of blades outwards and gains stealth for up to 2.5 seconds while gaining 40% movement speed. When Talon emerges from stealth, the blades converge on his location. When the ring of blades expands and contracts, enemies hit receive physical damage. Each enemy can only be damaged once at the start of the ability and once at the end.
